Transporter with locking device

Abstract

A transporter for a resectoscope for endoscopic surgery, wherein the transporter has a connection body and, for connection to a system component in the connection body, a latch system including an elongate latch element, which is arranged transversely with respect to the longitudinal axis of the transporter and has an engagement opening or an engagement groove, and a spring element, wherein one or more irrigation channels, arranged parallel to the longitudinal axis of the latch element, are formed between latch element and connection body. The invention further relates to a resectoscope for use in endoscopic surgery, wherein it includes a transporter according to one of the preceding claims and preferably a system component latched in the transporter.

The invention claimed is: 
     
       1. A resectoscope for use in endoscopic surgery, comprising:
 a transporter; and 
 a system component latched in the transporter,
 wherein the transporter comprises:
 a connection body and, 
 for connection to the system component, the system component being provided in the connection body, a latch system having an elongate latch element, 
 
 
 wherein the latch element is arranged transversely with respect to a longitudinal axis of the transporter and has an engagement opening or an engagement groove, and a spring element, 
 wherein one or more irrigation channels, arranged parallel to a longitudinal axis of the latch element, are formed between the latch element and the connection body, 
 wherein the one or more irrigation channels have both a first end and a second end and are open to an outside of the latch element at at least one of the first end and a second end of the latch element in order to allow irrigation liquid to flush the latch element and flow to the outside of the latch element, 
 wherein irrigation liquid is conveyable through the one or more irrigation channels from a lateral face of the transporter to a contralateral face of the transporter, 
 wherein the latch element includes two irrigation grooves, one on each axial side of the latch element, each of the two irrigation grooves arranged parallel to the longitudinal axis of the latch element and extending toward a same longitudinal end of the latch element, 
 wherein the connection body has the two irrigation grooves arranged parallel to the longitudinal axis of the latch element and adjoining the latch element, the irrigation liquid configured to be conveyed through the two irrigation grooves from the lateral face of the transporter to the contralateral face of the transporter, and 
 wherein the one or more irrigation channels are formed by the two irrigation grooves and extend over an entire length of the latch element. 
 
     
     
       2. The resectoscope according to  claim 1 , wherein the system component has an elongate shaft portion. 
     
     
       3. The resectoscope according to  claim 1 , wherein the latch system is designed for connection to the proximal end region of the system component. 
     
     
       4. The resectoscope according to  claim 1 , wherein the proximal end region of the system component is insertable into the engagement opening or engagement groove of the latch system. 
     
     
       5. The resectoscope according to  claim 1 , wherein the system component is an electrode instrument with an elongate shaft portion and with, at its distal end, an electrode to which high-frequency current can be applied. 
     
     
       6. The resectoscope according to  claim 5 , wherein the transporter is designed to control the longitudinal displacement of the work instrument. 
     
     
       7. The resectoscope according to  claim 1 , wherein the latch system comprises an elongate blocking element which is arranged, transversely with respect to the longitudinal axis of the latch element, in a blocking groove in the outer wall of the latch element. 
     
     
       8. The resectoscope according to  claim 1 , wherein the spring element is a compression spring, preferably a helical compression spring.
